I'm always up for more stuff with Ianto and Romana! And as far as the others go, Sora's a big animal lover too! He'd definitely volunteer to help out if Ianto ever wanted to do something for all the critters around Nautilus. And Pinocchio knows of at least a few stray cats that he could direct Ianto to if he ever makes a network post about wanting to open up a shelter or something similar :>
